Installed BE7.3 for SBS over 7.0. Initially GUI initialised okay but looking
at any device related item caused a Dr Watson. At this point NT backup refused
to see tape drive (Seagate 4mm DAT via Adaptec SCSI card). NT reported device
to be OK. Reinstalled drivers for tape device several times with no change.
Disabled all BE services and restarted server again. NT Backup saw tape
device and all was well. Started BE again and GUI generated Dr Watson immediately
as it launched.

I'm a real amateur at this game so any advice would be welcome.
Thanks
